Question

1. set up a punnett square using the following information:- dominant allele for purple corn kernels = r- recessive allele for yellow corn kernels = r- dominant allele for starchy kernels = t- recessive allele for sweet kernels = t- cross a homozygous dominant parent with a homozygous recessive parent6. using the punnett square in question #5:a. what is the probability of producing purple, starchy corn kernels?possible genotype(s)?b. what is the probability of producing yellow, starchy corn kernels?possible genotype(s)?c. what is the probability of producing purple, sweet corn kernels?possible genotype(s)?d. what is the probability of producing yellow, sweet corn kernels?possible genotype(s)?7. set up a punnett square using the following information:- dominant allele for normal coat color in wolves = n- recessive allele for black coat color in wolves = n- dominant allele for brown eyes = b- recessive allele for blue eyes = b- cross a heterozygous parent with a heterozygous parent8. using the punnett square in question #7:a. what is the probability of producing a wolf with a normal coat color with brown eyes?possible genotype(s)?b. what is the probability of producing a wolf with a normal coat color with blue eyes?possible genotype(s)?c. what is the probability of producing a wolf with a black coat with brown eyes?possible genotype(s)?d. what is the probability of producing a wolf with a black coat with blue eyes?possible genotype(s)?

For Question 5 & 6:

Step1: Define parent genotypes

Homozygous dominant parent: $RRTT$; Homozygous recessive parent: $rrtt$

Step2: Identify gametes

Dominant parent gametes: All $RT$; Recessive parent gametes: All $rt$

Step3: Fill Punnett Square

All offspring: $RrTt$

Question 6a:

Step1: Identify phenotype criteria

Purple (R_) + starchy (T_)

Step2: Calculate probability

All $RrTt$ match: $\frac{16}{16} = 1$

Question 6b:

Step1: Identify phenotype criteria

Yellow (rr) + starchy (T_)

Step2: Calculate probability

No offspring match: $\frac{0}{16} = 0$

Question 6c:

Step1: Identify phenotype criteria

Purple (R_) + sweet (tt)

Step2: Calculate probability

No offspring match: $\frac{0}{16} = 0$

Question 6d:

Step1: Identify phenotype criteria

Yellow (rr) + sweet (tt)

Step2: Calculate probability

No offspring match: $\frac{0}{16} = 0$

For Question 7 & 8:

Step1: Define parent genotypes

Heterozygous parents: $NnBb$ (x2)

Step2: Identify gametes

Each parent's gametes: $NB, Nb, nB, nb$

Step3: Fill Punnett Square

	$NB$	$Nb$	$nB$	$nb$
$Nb$	$NNBb$	$NNbb$	$NnBb$	$Nnbb$
$nB$	$NnBB$	$NnBb$	$nnBB$	$nnBb$
$nb$	$NnBb$	$Nnbb$	$nnBb$	$nnbb$

Question 8a:

Step1: Identify phenotype criteria

Normal coat (N_) + brown eyes (B_)

Step2: Count matching genotypes

9 matching genotypes: $NNBB, NNBb, NnBB, NnBb$ (variants)

Step3: Calculate probability

$\frac{9}{16}$

Question 8b:

Step1: Identify phenotype criteria

Normal coat (N_) + blue eyes (bb)

Step2: Count matching genotypes

3 matching genotypes: $NNbb, Nnbb$

Step3: Calculate probability

$\frac{3}{16}$

Question 8c:

Step1: Identify phenotype criteria

Black coat (nn) + brown eyes (B_)

Step2: Count matching genotypes

3 matching genotypes: $nnBB, nnBb$

Step3: Calculate probability

$\frac{3}{16}$

Question 8d:

Step1: Identify phenotype criteria

Black coat (nn) + blue eyes (bb)

Step2: Count matching genotypes

1 matching genotype: $nnbb$

Step3: Calculate probability

$\frac{1}{16}$
